Title: Message
Exactly what I had to do. I was skipping for 2 hours on failure, caching dns info, and doing
20 retries on 30 min intervals. Hotmail wasnt getting anything from me.
I switched back to letting my DNS server do the work (never really saw any benefit
anyway), turned off the skip on failure feature (also didnt make much of
a difference except to make my log files a little bigger) and increased my
retry to 24 times at one hour intervals. That immediately fixed the
problem.
I actually think things are running a
little better this way, likely because the extra effort the server does with
dns is offset by my longer retry interval. And I give mail a bigger chance to
get delivered to a problematic (or recently changed) mail server.

I also turned off
Failed Domain Skipping for the same reasons, but I don't believe
that I had any issues besides temporary delays causing confusion when helping
clients get their servers back online after failures. I figure that with
all the processing power that goes into spam and virus blocking, caching and
failed domain skipping aren't but 0.1% of the utilization and it's likely safer
to turn them off. Who knows.

Interestingly
enough, cacheing isn't the problem on our IMail side. Microsoft has not
removed the unresponsive hosts from their MX records despite the problem
persisting over a week and thosehosts never responding.
IfMicrosoft had changed their DNS, cacheing would be an issue.
Also, MSN
addresees would have the same queuing problem. The MX records for the MSN
domain(s) point to the Hotmail servers.
Since the
problem was particularly bad for us, we've put the dummy zone back in our mail
server's local DNS, with the 12,correction, 9out of 16 hosts that
do respond to us.
And no, I
won't share which 9 hosts with the mailing list, as I'm sure your subset of
hotmail servers would be different from mine, and these messages are archived
on the web for future admins to stumble over. If you really need to do
this too, look at the mail hosts and spend some time searching for those IP
addresses in your sys0521.txt log, but don't forget to check later and remove
your dummy zone when Hotmail returns to normal service.

I turned off IMail's
internal DNS caching in order to avoid situations like this. I don't host
that many local accounts, but I haven't seen any build-ups in my spool either
time that Hotmail has had issues. My thought is that maybe you cached
records in IMail that corespond to the servers that aren't functioning
properly? This is one of the reasons why I turned this off at least.
